The main content of this article is to explain "what is the reason why the linux CD-ROM drive should be mounted?" interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "what is the reason why the linux drive should be mounted?"

Because the linux system treats all hardware devices as files, when using the optical drive device, it must be mounted to the system in order to let the system identify the optical drive device; mounting is the process of merging the file directory of the linux itself with the file directory of the hardware device.

The operating environment of this tutorial: linux7.3 system, Dell G3 computer.

Why should the linux optical drive be mounted?

Because the Linux system treats all hardware devices as files, when using hardware devices such as optical drives, they must be mounted to the system so that Linux can identify them.

The so-called Linux system "everything is a file". All files are placed in a tree structure with the root directory as the root of the tree. In Linux's view, any hardware device is also a file, each with its own set of file systems (file directory structure).

When using these hardware devices in the Linux system, only by combining the file directory of the Linux itself with the file directory of the hardware device can the hardware device be used by us. The process of merging two into one is called "mounting".

How to mount Linux:

1. Enter: lsblk under root to view the hardware device.

2. Create a folder under / mnt.

3. Enter: mount / dev/sdb1 / mnt/usb. So it can be mounted.

If it is not mounted, the hardware device can be found through the graphical interface system in the Linux system, but it cannot be found on the command line.

Mount refers to connecting the top-level directory in the device file to a directory under the Linux root directory (preferably an empty directory). Accessing this directory is equivalent to accessing the device file.

To correct a misunderstanding, not any directory under the root directory can be used as the mount point, because the mount operation will make the files in the original directory hidden, so the root directory and the original directory of the system should not be used as the mount point. It will cause a system exception or even crash, and the mount point should be a newly-built empty directory.

The / dev/ directory file in the root directory is responsible for all the hardware device files. In fact, when the U disk is inserted into Linux, the system does assign a directory file (such as sdb1) to the U disk, which is located in the / dev/ directory (/ dev/sdb1), but you cannot access the U disk data directly through / dev/sdb1/. Accessing this directory will only provide you with some basic information (such as capacity) of this setting.

In short, any hardware device used by the Linux system must mount the device file with the existing directory file.

Note: in short, linux needs to start reading files from the root directory, external devices are not in the root directory, so they cannot be accessed. By mounting, external devices can be added to the root directory structure and can be accessed.

At this point, I believe you have a deeper understanding of "what is the reason why the linux optical drive should be mounted?" you might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
